Description

[Detailed description of the invention] [Industrial application field] The present invention relates to cleaning kitchen ducts.

[Prior Art] When hot air containing oil and fat from cooking passes through a kitchen duct, it sticks to the inner wall of the kitchen duct as oil dust, which can cause a fire.

Therefore, a technology to remove this oil dust is awaited.

[Problems to be Solved by the Invention] An object of the present invention is to provide a kitchen duct cleaning tool and cleaning method that can remove oil dust from the kitchen duct.

[Means to solve the problem] In order to achieve the above object, the present invention employs the following configuration.

(1) It has a wind receiving part that slopes downward toward the front, and
a housing having openings formed in the front and bottom; a nozzle fixed within the housing and configured to inject a cleaning liquid; a gouging blade attached to the front opening of the housing; and a cleaning blade to the nozzle. It is equipped with a hose for supplying irrigation fluid and for towing.

(2) By connecting an air suction device to the rear end of the duct to generate an airflow inside the duct, and pulling the hose of the kitchen duct cleaning tool inserted from the tip of the duct to a predetermined position, The inside of the duct is cleaned by scooping out the oil dust with the scooping blade while softening the oil dust by injecting the cleaning liquid.

(3) A housing having ring-shaped members arranged to face each other at a predetermined interval, and a wind receiving section that is horizontally suspended between the ring-shaped members and slopes downward toward the front, and an air flow that is rotatably supported within the housing and flows through the duct. The present invention comprises a radial fan which is rotated by a radial fan, a chain member attached to hang from the blade tip of the radial fan, and a traction means for performing traction.

[Operations and Effects of the Invention] <Regarding Claim 1> (Operations) When the wind blows against the wind receiving part, the cleaning liquid is injected from the nozzle, and the hose is pulled, the gouging blade removes the objects to be cleaned in the kitchen duct. to clean up.

(effect) It is possible to clean the objects to be cleaned in the kitchen duct.

<Regarding Claim 2> (Function) By connecting an air suction device to the rear end side of the duct to create a negative pressure inside the duct, an airflow is generated from the front end side of the duct toward the rear end side.

The cleaning tool is inserted from the tip side of the duct, and while the hose is loosened, the cleaning tool is moved by the airflow to a predetermined position to start cleaning.

The hose is pulled and the cleaning liquid ejected from the nozzle softens the oil dust, while the scooping blade scoops out the oil dust.

Wash away the scooped-out oil dust with cleaning fluid.

(Effects) The structure allows oil dust trapped inside the cleaning tool to accumulate.
Accumulated oil dust causes a problem in that the cleaning performance of the cleaning tool deteriorates, but since the present invention is configured to wash away oil dust with a cleaning liquid, the same cleaning performance can be maintained from the start to the end of cleaning.

Since the inside of the duct is under negative pressure, cleaning liquid, etc. will not leak out from the joints of the duct, etc.

<Regarding Claim 3> The radial fan is rotated by the airflow flowing within the duct. The chain member strikes the object to be cleaned. The object to be cleaned peels off from the inner wall of the duct due to the beating. Note that the wind receiving section provides power for backward movement.

[Example] A first example (corresponding to claim 1.2) of the present invention will be described based on FIG.

As shown in FIG. 1, the kitchen duct cleaning tool A includes a housing 1 having an approximately dustpan shape with openings 11 and 12 formed in the front and bottom parts, and a nozzle 2 fixed inside the housing 1. , a support blade 3 attached to the front opening 11 of the housing 1, and a hose 5 for supplying high-pressure hot water 4, which is a cleaning liquid, to the nozzle 2 and also for traction.

The housing 1 is made of lightweight metal such as aluminum, and has a wind receiver M13 whose upper surface is inclined forward downward at an angle of 20'' to 60 degrees.

The nozzle 2 includes four shower ports 21 that spray the high-pressure hot water 4 downward.

The dependent blade 3 is composed of a group of 16 adjusting forces 31 that are slightly curved downward and arranged in parallel at equal intervals.

The high-pressure hot water 4 has a temperature of 90°C and a pressure of 150k at the time of spouting.
g/cm2-200Kg/cm2.

The bottom of the hose 5 is made of a material with some visibility. Incidentally, four wires 61 for correcting the posture of the housing 1 are tied to the hose 5.

Next, how to use the kitchen duct cleaning tool A will be explained.

(1) Air suction I to the rear end side 62 of the kitchen duct 6! (not shown) to suck the air inside the duct.

As a result, an airflow 64 is generated from the front end side 63 of the duct 6 toward the rear end side 62.

(2) Place the kitchen duct cleaning tool A on the tip side 63 of the duct 6.
Insert through the duct opening (not shown) located at

(3) Loosen the hose 5 and move the cleaning tool A to the downstream end.

(4) When the hose 5 is dragged while injecting high-pressure hot water 4, the jetted high-pressure hot water 4 reaches the dependent blade 3 position, so the oil dust 60 at the dependent blade 3 position is softened, and the dependent blade 3 The oil dust 60 is removed and washed away to the rear end side 62.

(5) If there is a large amount of oil dust 60 adhering to the inside of the duct 6, loosen the hose 5, move the cleaning tool A backward, and pull it again to clean it.

Next, the effects of the kitchen duct cleaning tool A and the method of using the cleaning tool A will be described.

(a) Adjusting force 31 in which dependent blades 3 are arranged in parallel at equal intervals.
